“…Few studies have been reported on IL three-dimensional imaging; for example, a study was conducted for the acquisition of surface structural information of luminescent samples (e.g., lapis lazuli) using IL. [20] The author previously demonstrated that cathodoluminescence (CL) imaging, which uses the same mechanism as IL but with electron bombardment instead of ion bombardment, can provide two-dimensional images of non-metallic inclusions in steels, such as MgOAEAl 2 O 3 spinel, [21][22][23][24] Al 2 O 3 , [21][22][23][24] calcium aluminates, [25] rare-earth oxides (La 2 O 3 , CeO 2 , and Nd 2 O 3 ), [26] CaS, [25] BN, [27] and AlN [27] inclusions. This indicates that the IL images of these non-metallic inclusions could be obtained.…”

Obtaining information on the morphology, size, distribution, and chemical composition of non-metallic inclusions in steel helps control the steel production process and the quality of the steel products. Two-dimensional analysis is commonly used to acquire this information; however, more accurate data can be obtained through three-dimensional analysis, leading to a better control of the quality of steel products and their production process. Currently, several techniques are proposed for the three-dimensional analysis of non-metallic inclusions; however, they are time consuming. Herein, the author presented a method to rapidly obtain three-dimensional images of non-metallic inclusions in steel using ionoluminescence (IL). A three-dimensional image of MgO·Al2O3 spinel inclusions was constructed based on two-dimensional IL images obtained every 10 min during argon–ion bombardment. The proposed IL imaging can cover an oval-shaped area of 1.17 mm × 0.26 mm on the semi-major and in the semi-minor axes, respectively, at a single measurement. Three-dimension images of MgO·Al2O3 spinel inclusions with sizes more than 20 μm can be obtained within 4 hours. Therefore, the IL imaging proposed here can provide a precise and rapid account of the effects of non-metallic inclusions on steel products and the steel production process.
